Blazor 服务器身份验证问题：NotAuthorized 无法工作

Question

在我的 blazor 服务器应用程序中，我创建了一个自定义的authenticationStateProvider 来从我自己的数据库验证用户。它工作正常。但在我的 app.razor 页面中，我设置了 NotAuthorized 标记以将匿名用户重定向到登录页面，但不起作用。这是我的 app.razor 页面代码：

<CascadingAuthenticationState>
    <Router AppAssembly="@typeof(App).Assembly" AdditionalAssemblies="@_loadedAssemblies">
        <Found Context="routeData">
            <AuthorizeRouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)">
                <NotAuthorized>
                    <RedirectToLoginPage />
                </NotAuthorized>
                <Authorizing>
                    <span class="persianFontSans">Authorizing ...</span>
                </Authorizing>
            </AuthorizeRouteView>            
            <FocusOnNavigate RouteData="@routeData" Selector="h1" />
        </Found>    
        <NotFound>
            <PageTitle>The page not found</PageTitle>
            <LayoutView Layout="@typeof(MainLayout)">
                <NotFound />
            </LayoutView>
        </NotFound>
    </Router>
</CascadingAuthenticationState>

这是我的 customAuthenticationProvider 类：

public class SmartMISAuthenticationStateProvider : AuthenticationStateProvider
    {
        private readonly ProtectedSessionStorage _sessionStorage;
        private ClaimsPrincipal _anonymous = new ClaimsPrincipal(new ClaimsIdentity());

        public SmartMISAuthenticationStateProvider(ProtectedSessionStorage sessionStorage)
        {
            _sessionStorage = sessionStorage;
        }

        public override async Task<AuthenticationState> GetAuthenticationStateAsync()
        {
            try
            {
                var accountInfoStorageResult = await _sessionStorage.GetAsync<AccountInfo>("_accountSession");
                var accountInfoSession = accountInfoStorageResult.Success ? accountInfoStorageResult.Value : null;
                if (accountInfoSession == null)
                    return await Task.FromResult(new AuthenticationState(_anonymous));

                var claims = new List<Claim>();
                claims.Add(new Claim("AccountID", accountInfoSession.AccountID));
                claims.Add(new Claim("AccountType", accountInfoSession.AccountType));
                claims.Add(new Claim(ClaimTypes.Name, accountInfoSession.FullName));
                claims.Add(new Claim(ClaimTypes.MobilePhone, accountInfoSession.PhoneNumber));

                var claimsPrincipal = new ClaimsPrincipal(new ClaimsIdentity(claims, "SmartMISAuth"));
                return await Task.FromResult(new AuthenticationState(claimsPrincipal));
            }
            catch (Exception ex)
            {
                return await Task.FromResult(new AuthenticationState(_anonymous));
            }
        }

        public async Task UpdateAuthenticationStateAsync(AccountInfo accountInfo)
        {
            ClaimsPrincipal claimsPrincipal;

            if (accountInfo != null)
            {
                await _sessionStorage.SetAsync("_accountSession", accountInfo);

                var claims = new List<Claim>();
                claims.Add(new Claim("AccountID", accountInfo.AccountID));
                claims.Add(new Claim("AccountType", accountInfo.AccountType));
                claims.Add(new Claim(ClaimTypes.Name, accountInfo.FullName));
                claims.Add(new Claim(ClaimTypes.MobilePhone, accountInfo.PhoneNumber));
                claimsPrincipal = new ClaimsPrincipal(new ClaimsIdentity(claims));
            }
            else
            {
                await _sessionStorage.DeleteAsync("_accountSession");
                claimsPrincipal = _anonymous;
            }

            NotifyAuthenticationStateChanged(Task.FromResult(new AuthenticationState(claimsPrincipal)));
        }
    }

问题出在哪里，如何解决？ 预先感谢
